Technical Field

[0001] This application relates to the field of riveting processes, and in particular to an automatic riveting device. Background Technology

[0002] Riveting is a method of connecting multiple parts by using axial force to build up the shank of a rivet into a rivet head within the rivet hole. As a commonly used connection method, riveting plays a vital role in aerospace, automotive manufacturing, building structures, and machinery manufacturing. With continuous technological advancements and innovations, riveting technology will continue to provide efficient and reliable connection solutions for industrial production.

However, manual riveting relies heavily on workers' manual operations, including steps such as inserting the rivet, positioning with a top die, and riveting to form the part. These steps require precise operation by workers and demand a certain amount of time and physical strength. Prolonged repetitive labor can lead to worker fatigue, thereby reducing production efficiency. Summary of the Invention
